The keyboard and trackpad are connected to the motherboard. Before removing the keyboard and trackpad, disconnect both components from the motherboard, as shown in the following step.
Very poor & sketchy guide! NO mention at all of how to handle the other wires involved in disconnecting the screen (lid) from the laptop base, eg: the wireless antenna connections and instructions like: "Unscrew the screws holding it down" are far too vague! holding WHAT down ffs!!!!
